I can safely do this because the pipeline is only used for seeking + pulling samples and can therefore safely be put into NULL state before restructuring. </span></div> <div> </div> <div><span>This was the best solution for minimizing overhead. In contrast, using input-selector caused a storm of read operations on my source side, for reasons I do not understand. I assume input-selector is the solution of choice for switching during playback, and to that end it performs some magic which is detrimental in my case.<br></span></div> <div> </div> <div><span>thanks,</span></div> <div><span>Chris</span></div> <div> </div> <div>Agostinho <sergio.r.agostinho@gmail.com> hat am 20.
